Title: Improvements in and relating to unsaturated polyesters
IPC: C08G63/553
Filed: 1962-02-19
Abstract: Unsaturated polyesters are made by reacting an a , b -unsaturated dicarboxylic acid or anhydride with a polyhydric alcohol and dicyclopentadiene at a temperature below the boiling point of dicyclopentadiene (viz. 142 DEG C.) until all or the major portion of the dicyclopentadiene has been reacted by an addition reaction, and then heating the reaction mixture to above 160 DEG C. until esterification is substantially complete. Instead of the dicarboxylic acid and the polyhydric alcohol, there may be used an ester derived from equi-equivalent proportions thereof. Specified unsaturated dicarboxylic acids are maleic, fumaric, itaconic, mesaconic and citraconic acid. Specified polyhydric alcohols are ethylene-, diethylene-, propylene- and butylene-glycols; 2:2-dialkylpropanediols; 1:6-hexane-diol; 1:4-butenediol; dimethylolbenzenes and alkyl substituted derivatives thereof; 4,41-dihydroxy-dicyclohexylalkanes and bisglycol ethers thereof; the bisglycol ethers of 4,41-dihydroxy-diphenylalkanes which may be substituted in the 3,31-position by alkyl or allyl groups; trimethylolpropane; ethers and esters of polyhydric alcohols containing three or more hydroxyl groups; and dimethylol endomethylene cyclohexene.  The reaction mixture may also include (a) a saturated polycarboxylic acid e.g. an aliphatic hydrocarbon dicarboxylic acid, a benzene dicarboxylic acid or hydrogenation product thereof, tri- or tetra-chlorophthalic acid, trimellitic or pyromellitic acid or esters of polycarboxylic acids with more than two carboxyl groups; (b) saturated or unsaturated monocarboxylic acids; (c) saturated or unsaturated monohydric alcohols; (d) an ester of a fatty acid with glycerine or another polyhydric alcohol; or (e) the reaction product of 2 mols of an alkylene oxide with aniline or p-toluiline which acts as a "built in accelerator" in the subsequent copolymerization. The reaction may be effected in the presence of a triaryl phosphite, an esterification catalyst or an azeotroping liquid.  The polyesters may be copolymerized with unsaturated monomers, e.g. styrene or its nuclear alkylated or chlorinated derivatives, a -methyl styrene, vinyl esters, acrylic and methacrylic esters, allyl esters, or vinyl pyrrolidone.  Copolymerization is effected in the presence of the usual peroxide catalysts and accelerators. The copolymerizable composition may be admixed with fillers (e.g. asbestos, ground glass, chalk, silicon carbide or sawdust), dyestuffs, pigments, a silicone oil or a melamine resin. They may be used in the manufacture of coatings, castings and glass fibre laminates. Examples are given.

Title: Improvements in or relating to transmission belts
IPC: F16G5/08
Filed: 1924-03-12
Abstract: 239,554. White, A. E., (General Motors Research Corporation). March 12, 1924. Belts. - A V-driving belt is composed of superposed layers of fabric &c. secured together by vulcanized rubber, the edges of the layers forming the driving surface. The layers are preferably of different degrees of stretchability, the medial layers 21 being substantially non - stretchable, the outer layers 23 having residual stretchability to allow of extension when passing round a pulley and the inner layers 22 being capable of contraction without buckling. The medial layers may comprise straight-laid square woven fabric either tightly woven to avoid stretching or loosely woven and stretched, or they may be formed of longitudinal threads secured together in any suitable manner or of cord convolutions in layers and preferably in contact. The inner and outer layers are formed of loosely-woven strips, the crossthreads being formed with a relatively tight twist to impart transverse rigidity or they may comprise strips of fabric cut on the bias preferably at an angle of 45‹. Different weaves mav be employed in the inner and outer layers. The inner layers are given an initial stretch to produce a tendency to contraction, and the outer layers are slightly stretched to avoid buckling when the belt is straightened. Either the inner or outer layers may be omitted. The rubber banding material is preferably applied as a skin coating to avoid a large rubber content. The belt may be formed by joining the various layers end to end and winding the length under tension on a drum 31 to form a cylinder which after vulcanizing is cut into a number of V-shaped endless belts. The tension may be applied by a brake drum 18 and the stretch when winding the successive layers may be regulated by adjustment of the weights 38 acting on the brake band 39. An oil-resisting rubber compound may be employed. The belt is stated to retain its trapezoidal cross-sectional shape when bent round a pulley. Reference has been directed by the Comptroller to Specification 19934/12.

Abstract: 1355628 Detecting coherence within a pulse train THOMSON-C S F 14 Feb 1972 [16 Feb 1971] 6740/72 Heading G1U In a method of testing whether the pulses of a train of pulses, each of which comprises a burst of a relatively high frequency carrier signal, are coherent with each other, the pulse train I, Fig. 1, is applied in parallel to an envelope detector E, which detects the average D. C. level of the pulses, and to a narrow pass-band filter F, whose centre frequency is swept over a range including the pulse carrier frequency so that when the pass-band includes the carrier frequency a peak is produced in the filter output, and the two resulting signals are compared, for example by being displayed on a c.r.t., the presence of coherence between the pulses being indicated by the fact that the magnitude of the peak from the swept filter equals the average D. C. level from the envelope detector. In the preferred embodiment, the effect of a swept filter is achieved by mixing the input signal with quadrature outputs of a swept oscillator, applying the mixed signals via fixed narrow pass-band filters to square law detectors and summing their outputs. Further, rather than directly displaying the resulting signal as in Fig. 1, an adjustable fraction of the average D. C. level extracted from the two mixed signals is first subtracted from it.
